c1223- malfunction in abs control
c1251- pump motor is locked/open circuit
c1252- hydroboost pump motor malfunction
c1256- accumulator low pressure malfunction

Sounds about right, check EBAY or online for a cheaper one.

Thank you for sharing your thoughts. Your article shows tells me you must have a lot of background in this topic.

 

I purchased a used abs pump/master cylinder unit on ebay and had it delivered to Nova Scotia, and then paid a mechanic to install it. All together for the part, delivery and repair cost me about
$1100 after tax. Not bad at all considering Toyota wanted 4000 plus tax just to buy the part.

It has been working great ever since.
